Hello to All, I bring greeting to you all from Jamestown, SC. I am somewhat new at raising chickens. I have read alot of the posted messages that many of you listed and I am very thankful. I would like to know if and what types of preventive measures should be taken with chickens as it relates worming medication or anything that should be given to prevent disease. I have 20 barred rocks (15 pullets & 5 roos) that are 12 weeks old and they are just beautiful . I just want to make sure that I am doing all that I am supposed to be doing to ensure their continued health and safety. Thanks for all of your input.
